  When such a prior art is used, even if a protruding knob is formed on the bottom surface of the inner lid, it is difficult to pick the knob with sufficient force to remove the inner lid from the outer lid, and an auxiliary tool such as pliers is used. There was the inconvenience of having to use it. In addition, the tongue-shaped knob that can be raised requires an auxiliary tool such as a flat-blade screwdriver or a cone to create the first clue for the raising operation. However, there is a problem that it is not easy to apply a necessary and sufficient force.

  Accordingly, an object of the present invention is to provide an inner lid of a drying container that can be easily detached from an outer lid with only fingers by providing an operation portion that can be raised on the bottom surface in view of the problems of the prior art. It is in.

  The configuration of the present invention for achieving such an object includes a bottomed cylindrical main body portion that stores a desiccant, and a retractable operation portion that is formed on the bottom surface of the main body portion. The gist of the invention is to form a plate shape that covers a part of the bottom surface from the outside and opens a ventilation opening formed on the bottom surface.

  In addition, the operation part can be formed in the shape of a hook for fingers or a tongue for picking.

  Moreover, a clearance gap may be formed between an operation part and a bottom face, and you may hold | maintain in parallel with a bottom face via the holding | maintenance part which fractures | ruptures when it raises.

  Furthermore, the outer edge of the operation part can be made substantially coincident with the outer periphery of the main body part, and the main body part has the same height all around the ribs extending to the base end side of the operation part and the operation part. Can be formed.

  According to the configuration of the invention, the operation portion formed on the bottom surface of the main body can be easily formed sufficiently large except for the ventilation opening formed on the bottom surface. Sufficient force can be applied and there is no need to use auxiliary tools such as pliers. That is, the inner lid can be easily removed from the outer lid with only fingers, and the outer lid, the inner lid, and the desiccant can be appropriately separated. The operation part can be formed in the shape of a hook for hooking or a tongue for picking as long as the opening for ventilation on the bottom is not blocked. The operation of removing the inner lid is easier.

  The operation unit can be connected to the bottom surface of the main body part via the base end side connection part, so that the operation part can be connected sufficiently strongly to the bottom surface. There is no risk of inadvertent separation from the bottom.

  The operation part can be caused more easily by fingers by forming a gap with the bottom surface. In addition, the operation portion is provided with a holding portion that is broken when it is raised, so that there is no possibility that the operation portion will be turned up carelessly before being raised. The operation portion is formed with a non-slip on the surface on the raising side, so that it can be easily picked up when it is raised, a sufficient force can be applied even in the form of a tongue piece, and a comfortable touch can be obtained.

  If the outer edge of the operation part is made to coincide with the outer periphery of the main body part, the size of the operation part can be maximized, and a large area required for picking or inserting the finger can be realized more easily. It should be noted that the outer edge of the operation portion may be partially projected from the outer periphery of the main body portion, particularly at the tip portion thereof.

  The main body portion can be stably supported on a belt conveyor or the like when the desiccant is accommodated, for example, upward by forming the entire circumference at the same height.

  The inner lid 10 of the drying container is formed with an operation portion 13 outside the bottom surface 12 of the bottomed cylindrical main body portion 11 (FIGS. 1 and 2). However, the illustrated operation unit 13 is formed in a hook-like hook shape.

  The inner lid 10 stores the desiccant K and is used by being detachably mounted on the top surface of the outer lid 20. The inner lid 10 is integrally formed of a plastic material having appropriate elasticity such as low density polyethylene.

  An outer flange 14 is formed at the upper end of the main body 11. The distal end portion of the outer flange 14 is formed into a thin flange portion 14a by obliquely cutting the upper surface side, and a small rib protruding symmetrically on the upper surface and the lower surface of the outer flange 14 on the inner side of the flange portion 14a. 14b and 14b are formed. In addition, circumferential ribs 11 a and 11 a are formed in two upper and lower stages on the inner periphery of the main body 11.

  .. Are formed in the center of the bottom surface 12 for ventilation. The openings 12a, 12a,... Are divided into four circular holes by support branches 12b, 12b intersecting in a cross shape, and a molding gate 12c is formed at the intersection of the support branches 12b, 12b. .

  The openings 12a, 12a ... are closed from the inside by a breathable mesh member 12d. The mesh member 12d is, for example, a long fiber nonwoven fabric such as polyester fiber, polypropylene fiber, or nylon fiber, or a mesh cloth or Japanese paper made of the same material, and is a mold that opens and closes when the inner lid 10 is injection molded. By sticking to one wall surface in the cavity, it is possible to insert-mold integrally with the inner lid 10 simultaneously with the injection of the molten resin.

  The operation unit 13 is formed in a curved plate shape that partially covers the openings 12a, 12a,... And covers the entire surface of the openings 12a, 12a,.

  The operation part 13 is formed in a semicircular arc shape whose outer edge coincides with the outer periphery of the main body part 11. The proximal end side of the operation unit 13 is connected to the bottom surface 12 via connection portions 13a and 13a parallel to the diameter of the bottom surface 12 (FIGS. 1 and 3). The operation portion 13 is held in parallel to the bottom surface 12 via the gap g by forming holding portions 13b, 13b having a small cross-sectional triangle in the middle portion. Each of the holding portions 13b and 13b is disposed along the inside of the operation portion 13, and the operation portion 13 can be pulled upward by breaking the holding portions 13b and 13b (see FIG. 1 two-dot chain line).

  The leading end portion of the operating portion 13 on the pulling side is expanded in width by providing a straight portion parallel to the connecting portions 13a and 13a on the inner side, and on the surface of the wide leading end portion, a parallel rib-shaped anti-slip 13c, 13c ... are formed. Further, on the side of the bottom surface 12 where the operation unit 13 is not provided, a rib 12e extending to the base end side of the operation unit 13 is formed along the outer periphery of the bottom surface 12, and the rib 12e is connected to the surface of the operation unit 13. It is the same height. That is, the entire circumference of the main body 11 is finished to the same height via the rib 12e and the operation unit 13.

  The outer lid 20 is formed in a shallow dish shape slightly deeper than the inner lid 10 (FIG. 2). .. Are formed on the outer periphery of the outer lid 20, and a female screw 22 and a ring-shaped engagement rib 23 above the female screw 22 are formed on the inner periphery.

  The inner lid 10 can be detachably mounted on the top surface of the outer lid 20 by storing the desiccant K in the main body 11 and pushing it into the outer lid 20 in parallel (FIG. 4). At this time, the outer flange 14 of the inner lid 10 fixes the inner lid 10 by the thin flange portion 14 a at the tip getting over the engagement rib 23 of the outer lid 20, and the desiccant K is applied to the top surface of the outer lid 20.
